Liberty Ross is refusing to cower at home and hide from the Hollywood scandal over her director husband Rupert Sanders’ affair with “Twilight” star Kristen Stewart.

On Wednesday night, Ross stepped out — without her wedding ring — to the LA premiere of “Lawless.” She went with brother Atticus Ross, a member of rock band Nine Inch Nails. Observers said she looked “gorgeous” and “relaxed,” at the DeLeon Tequila event also attended by the movie’s stars, Shia LeBeouf and Guy Pearce.

Liberty, a model and mother of two, is friends with Susie Bick, the wife of “Lawless” writer and composer Nick Cave.

After Sanders was caught on camera last month kissing Stewart, who starred in the Sanders- directed “Snow White and the Huntsman,” friends tell us Ross is refusing to let his infidelity tear her apart.

“She won’t hide at home,” a source tells us. “Liberty has shown incredible grace going through a difficult situation where all the intimate details are very public.”

Friends say Ross and Sanders are having marriage counseling, and he is begging her to forgive him. But Liberty is taking her time to work out her feelings and to ultimately decide what would be best for their kids.

“She is a very emotionally smart woman. She knows she can take her time and make her own decision, one that would be the best for her and her family, and not be persuaded by what other people, and the media, think of her and the situation,” a source told us.

Our source added that it’s still unclear whether the couple will reconcile. “One thing that is clear is that before this, Rupert and Liberty had a wonderful relationship . . . One affair does not erase a 10-year history and many shared experiences together. It is just whether they are strong enough to weather it.”

Meanwhile, Robert Pattinson confirmed that he’s moved out of the love nest he shared with Stewart, joking with Jimmy Kimmel that he’s “homeless.”
